主　　题：Nearshore process Rip current Al-Nakheel beach Delft3D model 

摘      要：Al-Nakheel beach is located northwest of Alexandria city,Egypt,along the Mediterranean *** the period from 1998 to 2003,seven detached breakwaters were constructed along Al-Nakheel beach to create a sheltered area for ***,the structures amplify rip currents,shoreline accretions,and *** aim of this research is to track the variations of the rip currents within the study area and show the effects of the breakwaters on the *** research is based on the hydrodynamic and morphological data of the study area and uses the Delft3D hydrodynamical model combined with other data analysis tools to serve the model *** data include measured sea-level observations in 2013,the ERA-interim wave datasets from 2015 to 2018 and wind data in 2018,bed morphologies,and Google Earth satellite images from 2010 to *** model is calibrated on the basis of the available current measurements within the nearshore *** show that the shoreline eroded at an average rate of about 0.9 m/***,pairs of vortices are formed behind the breakwaters with an average current velocity of 0.6 m/*** predominant northwest waves induce rip currents on the leeside of the structures with velocities reaching 1.2 m/s,associated with the rip pulsation that extends *** problem solution decision recommends the removal of the sand deposition on the leeside of the breakwaters by an average amount of 100000 m3/yr and the fencing of the safe area for swimming by a floating fence of 1000 m length and 65 m average width.
